A girl who destroys the cock. She invites you in, as if to offer you seductive oral sex, then attacks the penis with an unfathomable amount of force.

After said mongling is done the CM returns to her cave down the hatchet and stays up all hours of the night practicing her evil tongue swaths on helpless bananas. After she wakes up, hungry for more cock, she spends the daylight hours searching for her next prey.

The cycle then repeats again.

Me: Lindsey, you're roommate, Marissa, is such a cock mongler!
Lindsey: I know. The smell of twisted cock is all over my room. That's why I'm staying over at Taeler's house.
